MOTOR VEHICLE.

Application filed June 14, 1923.

To all whom it may concern Be it known that we, EDGAR W. VVooo- \VARD and JOHN C. MILLS/in, citizens of the United States, and residents of Susan-ville, California, have invented certain new and useful Improvements in Motor Vehicles, of which the following is a specification.

Our present invention relates to improvements in motor vehicles of the type designed to enable the motor to be used as a source of external power, and is designed more especially to provide means by which the car will be especially adapted for the use of plumbers, enabling them to have the power operated means associated with the machine forv cutting and threading a pipe, although not limited to this specific use. The invention has also been developed in connection with the Ford motor car, but is not limited to this particular machine.

The invention comprises the novel features of construction and arrangement and combination of parts hereinafter described and particularly defined in the appended claims.

In order that the invention may be more properly understood, we have illustrated the same in the accompanying drawings in which- Figure 1 is a plan view showing in a conventional manner a suflicient portion of the automobile frame and transmission housing to illustrate the application of our invention. Fig. l is an enlarged sectional detail.

Fig. 2 is a side elevation of the housing as viewed in the direction of the arrow Figure 1. 1

Fig. 3 is a detail view showing the clutch mechanism,

Fig. 4 is a detail plan view showing a modified form in which a shaft drive is used instead of a chain drive.

Fig. 5 is a side view of the same looking in the direction of the arrow Fig. 4:, and i F ig.'6 is a view similar to Fig. 4, but with the enclosing housings omitted.

Referring by reference characters to these drawings, the numeral 1 designates the usual frame of the Ford automobile, and 2 the rear part of the transmission housing, which, it will be understood, carries at its rear end the usual semi-spherical member of the universal joint casing which is indicated at 3,

the engine shaft which projects into this member 3 being indicated at 4, and being Serial No. 645,469.

provided with a squared socket 4 which receives the squared end of the shaft to be drivenv 5 designates the usual propeller shaft. In carrying out the present invention, this shaft is shortened or cut off suificiently to allow the back half of the universal joint housing indicated at 3 to be moved far enough from the front half or section to provide for the interposition of our improved power transmitting mechanism.

. To this end we provide a cylindrical housing 6 having its end adapted to cooperate with the housing members 3, 3, the ends of the cylindrical housing 6 being provided with flanges 6 to cooperate with the peripheral flanges of the sections 3 and 3, the whole being held together by long bolts 7 which take the place of the usual Ford universal housing bolts. It will be understood that the usual universal joint indicated at 8 is provided, secured to the forward end of the propeller shaft 5 shortened as above described, and the rear end of the housing 6 may be provided with an interior auxiliary universal joint housing member 3 to cooperate with the portion 3 to form the grease chamber for the universal joint 8.

Within the housing 6 above described, we provide an auxiliary shaft 9 which has a squared portion 9 fitting the square recess 4; in the end of the engine shaft. This shaft section 9 has at its rear end a squared portion 9 which is provided with a cylindrical recess 9 within which fits the reduced cylindrical end 10 of the squared shaft portion 10, which latter is connected with or forms a part of the universal joint oonnectionto the propeller shaft. The squared shaft portimes 9 and 10 are of exactly the same size to receive a shifting sleeve 11 which has an opening therethrough of square cross section, corresponding to parts 9 and 10. Shaft 9 is further provided with round or cylindrical portions 9 and 9*, the latter being of larger diameter, and co-operating with these is a power transmitting element, in the present instance, a sprocket wheel indicated at 12, which has an opening through the center thereof, one portion of which, 12, is squared to fit the square portion 9 and the shaft 9, while the other portion 12 is cylindrical to fit the cylindrical portion 9.

The elements 11 and 12 are provided with the customary annular grooves which receive the forks of the double shifting fork llheso parts 1 and 12 are so proportionec. in relation to the shaft parts hercinbefore described, that when the c utch fork ill moved backward or to the limit of its move:

ment, towards the right 1-3, sleeve or clutch member 1.1 will be moved ack over squared portion 10' and by its engagement with square shaft portions '9 and 10. will couple these together, andcause them to retate in unison. it the same time power ele ment .12 will have been moved backward or t the right, Fig. '3 until stopped by flange 9, at which time the squared portion 12 of power element 12 will have been disenaged from the square portion 9" of shaft and will be in ali nmen' th the round portienl) of the shaft, whereby will be free to revolve without ro power element 12. In this positi: may be driven in the ordinary WV hen, however, the clutch operati member 13 is shifted forward to left, Fi 3, the power element will caused to engage the squared portion a of the shaft, and be rotated thei while sleeve or member 11 will be I j from the squared portion 14), the limit of movement of member 11 to the left bei g determined by flange 9. i' l ith the parts in this position, and as shown in the operation of the engine will d in she i; 9 and power transmitting element 12. with-- out driving the propeller shaft of the automobile.

The power transmitting element 12 may be used for transmitting power for any desired purpose, but as we have had in mind adapting the machine for plumbers use, we have shownitherein as adapted for operating the pipe threading and cutting means. To this end we have secured to the frame an automobile an auxiliary frame, preferably formed of tubular or pipe members as shown, and comprising longitudinal men:- bers 14E and connecting members 14%, these latter embodying tubular portions 1 1 and through which a pipe may be slid as dicated at 15, Fig. 1. The opening in the ember 14B is made large enough to form a urnal for a hollow chuck indicated at which chuck carries a sprocket wheel 0 designed to be driven by sprocket chain 16, from the sprocket wheel 12, this chuck also carrying means of any suitable type as indicated by set screws 15 which may be screwed in to impinge against the pipe, and lock it to the chuck so that it will be rotated thereby.

Frame members 14 are provided with slidable cau-iers for a threading die or dies, such carriers being indicated at 17 and 17 and having the ordinary plumbers stock and die secured thereto by short pipe sections 16 substituted for the usual handles, so that as the pipe is threaded, the dies will move relative to the pipe, the pipe being held against longitudinal movement by the chuck.

Instead of using a chain and a sprocket drive as shown in the figures above referred to, we may use a bevelled gear and shaft drive as shown in Figs. 4, 5, and 6, in which event we substitute for the sprocket wheel 1:2 a bevelled gear 12 which meshes with a bevelled gear 16*, fast on one end of a shaft 17 which preferably through the interposition of a clutch member 18 drives a worm 13) which mesh s with a worm gear v2O, carried b y the chuck member. 111 this construction we preferably provide the shaft 17 with a housing 21 bolted to the housing 6* at one end and to a worm gear housing 22 at the opposite end. The housing 21 is provided with a slot in its upper side to accommodate the shifting fork for operating the clutch member 18, and in this form the Worm gear is stopped and started by the clutch 18, bevel gear 12 being fast on the auxiliary shaft.

By the use of the construction hereinbefore described, it will be obvious that the motor car may be driven in the usual manner to the place of work, and then by merely shifting the clutch 13 to connect the power transmitting element 12 with the shaft 9, the apparatus may be used for external power purposes, and it will be obviousthat by using either of the forward or reverse drives of the car, the power transmitting element may be rotated in either direction at will.

In the above description where we use the term engine shaft, it will be understood that we do not refer to the crank shaft, but refer to the shaft member which is operated by the transmission mechanism.

Gbviously in the form shown in Fi s. 1 and the parts are so disposed that when sprocket 12 is clutched to shaft 9 or in driving position, it is aligned with sprocket 153, preventin any binding or distortion of the sprocket c ain.

Having thus described our invention, what we claim is:

1. ln a motor vehicle of the Ford type, the COHlblDZLillOil with the transmission housing and transmission shaft, of a cylindrical casing secured to said housing and carrying a universal joint housing at its rear end, a propeller shaft having a universal joint in said housing provided with a non-circular shaft section, an auxiliary shaft in said cylindrical housing having its front end conllli nected with said transmission shaft and its rear end non-circular aligned With said noncircular shaft section, a sleeve having a nonciroular bore filling said non-circular rear end and slidable to engage said non-circular shaft section, said auxiliary shaft having a power transmission element slidably carried thereby With means for causing it to be looked to the transmission shaft in one position, and released therefrom in another position, and means for shifting said power transmission element and sleeve in unison.

2. In a motor vehicle the combination with the main frame and propeller shaft, of an auxiliary frame secured to said main frame, and projecting from one side thereof, a rotary member journalled in said auxiliary frame on an axis parallel With the propeller shaft, and means. for driving said rotary member from the engine.

In testimony whereof, We aflix our signatures.
